Activities of protease (A) and glucanase (B) in 3-day old barley seedlings after CAPP treatment. Variants: C—control/untreated barley grains; O10–O300: barley grains treated with plasma generated in oxygen atmosphere for 10, 20, 30, 60, 180 or 300 s; A10–A300: barley grains treated with plasma generated in ambient air for 10, 20, 30, 60, 180 or 300 s; N10–N300 barley grains treated with plasma generated in nitrogen atmosphere for 10, 20, 30, 60, 180 or 300 s. Different letters indicate significant difference at p-value < 0.05, bars are means of ten experimental runs (one run represents 50 seeds per variant; three 1.5-g mixed samples were analyzed per experimental run and each variant for protease and glucanase activities) ± SD according to Tukey’s HSD test.
